HENRY GINNEL OF GARDEN CITY, NEW YORK.

BOW FOR WATCHES.

Specification of Letters Patent.

Application filed May 7, 1908.

Patented Dec. 29, 1908.

Serial No. 431,441.

- To all whom it may concern:

p Beit known that I, HENRY GINNEL, a citi- Zen of the United States,residing at Garden City, in the county of Nassau and State of New York,have invented certain new and useful Improvements inBows for lNatches,of which the following is a specification.

This invention relates to an improved bow for watches, and moreespecially to certain improvements in the bow for watches for which anapplication for Letters Patent was filed by me on March 13, 1908, SerialNo. 420,960, the improvements being designed with a view of facilitatingthe detaching of the bow from and the replacing ofthe bow on thependant, so that either an ordinaryT bow or a brooch-bow may be used, asdesired; and for this purpose the invention consists of a bow forwatches which comprises a capshaped bridge 'provided with recessedextensions at diametrically-opposite points, sliding and headed pinsguided in the ends of the bow, said extensions engaging the inner headsof the pins, so as to permit the detaching of the inner ends of the pinsfrom the interlocking extensions when the bridge is lifted clear of thepins.

The invention consists further of certain details of construction whichwill be fully described hereinafter and finally pointed out in theclaims.

ln the accompanying drawings, Figure 1 represents a verticallongitudinal section of my improved bow for watches drawn on an enlargedscale, Fig. 2 is a similar section showing the bow in position forpermitting its detachment from the pendant, Fig. 3 is a rear-elevationof the bow made in the shape of a chatelaine-brooch, Fig. 4 is a detailperspective view of the bridge and extensions for locking the bow inposition on the pendant, Fig. 5 is a plan-view of Fig. 4, Fig. 6 is adetail sectional side-elevation of one of the interlocking pins at theend of the bow, and

Fig. 7 is a perspective view of the interlocking pin shown as detachedfrom the bow.

Similar letters of reference indicate corresponding parts throughout theseveral figures.

Referring to the drawings, a represents the stem, t the bow, c the crownand d the pendant of a stern-winding watch. The bow l) is provided withsleeve-shaped ends t1 having socket-recesses b2 at the inner ends. Thesleeve-shaped ends b1 serve for guiding horizontally-sliding pins b3which are provided with enlarged heads b4, and which are recessed atopposite sides at b5 adjacent to the inner heads, as shown clearly inFigs. 6 and 7. The upper part of each pin b3 is flattened at t so as tobe guided in the correspondingly-shaped interior portion of the seeve-shaped end t1 without turning on its axis on the same. On thependant d is guided a cap-shaped bridge e, which is provided with anopening in its top-part for the upper end of the stem o and withhookshaped extensions e1 at diametrically-opposite points, saidextensions being recessed so as to permit the insertion of the innerheads of the bow-pins b3 and the interlocking of the ends by theparallel elongated ends e2 of the extensions which are arranged closelytogether so as to engagevthe reduced necks b5 of the pins b3. Theextensions e1 are shown in Figs. 4 and 5. When the bridge is placed inposition on the stem it is held between a collar al on the upper end ofthe pendant and the crown, the recessed extensions interlocking with theinner heads and the reduced portions of the pins, so as to hold the bowrigidly in position on the boatf.

The stem a is provided with the usual annular notches "o, nl, which areengaged by a split spring-sleeve g the upper end of which is screwedinto the pendant, while the lower ends of the spring-sleeve serve forsetting the stem for winding the watch or setting the hands. In additionto the notches n, al, a third annular notch "n.2 is arranged on the stembelow the notch nl, which third notch serves for ermitting anotherupwardlyshifting motion of the stem so as to bring the same with thebridge e and crown c in raised position, as shown in Fig. 2, and permitthereby the clearing of the recessed extensions of the bridge from theinner heads and recessed portions of the pins b3, so that the latter canthen be removed through the openings in the boat by moving the pins inoutward direction into the position shown in Fig. 2, so that the bowclears the outer ends of the boat and can be detached for repairs orexchange with a brooch-bow 7L, as shown in Fig. 3. For re-inserting thebow, the pins at the ends of the same are placed in line with theopenings in the ends of the boat and then pushed inwardly. The bridgeand bow are then returned, by downward pressure on the bow, in downwarddirection, so that the recessed ends of the bridge rengage the headedends of the pins and the recessed portions adjacent to the inner headsof the same and reestablish thereby the locking connection between bow,bridge and boat. The elongated extensions of the bridge serve as guidesfor the inner recessed ends of the pins so as to secure the lockingconnection of the bridge with the same and for holding the ends of thebow rmly in locked position in the boat.

The improved locking arrangement for the bow can be applied to anystem-winding watch at present in use provided that the additional notchn2 is added to the stern and the sliding headed ins are applied to thesleeveshaped ends oi the bow. rIhis detachable connection of the bowwith the pendant permits also the use of the watch with an ornamentalbrooch-bow, which can be readily exchanged with the ordinary bow, sothat one and the same watch can be carried either on a chain or on thegarment by the chatelaine brooch-bow. The detaching or reattaching ofthe bow can be accomplished with the same facility as the setting of thewatch, and forms there by an attractive feature for mens and ladieswatches, especially as a solid swivel-link can be used with the bow inplace of a swivel-link with a spring-snap, which frequently opens andpermits the accidental or unintentional disconnection of the watch fromthe chain, while for ladies use the Watch can be used with an ordinarybow or an ornamental bow, as desired. l

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. rIhe combination, with the stem and pendant of a watch, of a bowprovided with sleeve-shaped lower ends, headed pins guided in saidsleeves, and a bridge turning on the stem and provided with recessedextensions at diametrically-opposite points for interlocking with theinner headed ends of the pins at the ends of the bow.

2. In bows for watches, the combination, with the stem and pendant of awatch, of a bow provided with sleeve-shaped lower ends, headed pinssliding in said recesses, means for preventing the axial motion of saidpins, and a bridge turning on the stem provided with recessed extensionsat diametricallyopposite points for interlocking with the inner headedends of the pins at the ends of the bow.

3. In bows for watches, the combination, with the stem and endant of awatch, of a bow provided with s eeves at its ends, headed pins slidingin said recesses and provided with reduced portions adjacent to theinnei1 heads of the same, means for preventing the axial motion of saidpins, and a bridge turning on the stem provided with recessed extensionshaving upwardly-extending portions for interlocking with the inner headsand recessed portions of the pins.

4. In a bow for watches, the combination, with the stem provided withnotches for winding the watch and setting the hands with an additionalnotch for permitting the release of the bow, of a pendant, having aspring-sleeve engaging said notches, a bridge located on the stem andprovided with recessed extensions at diametrically-opposite points, abow provided with sleeve-shaped ends, and headed pins sliding in saidends,

5. In a bow for watches, the combination, with the stem provided withnotches for winding the watch and setting the hands and with anadditional notch for permitting the release of the bow, of a pendanthaving an interior spring-sleeve, a bridge located on the stem andprovided with recessed and vertically-elongated extensions, a bowprovided with sleeve-shaped ends, and sliding pins, guided in the endsof the bow and having headed ends, flat upper faces and contractedportions adjacent to the inner heads for ene gaging the recessedextensions of the bridge.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.

HENRY GINNEL.
